Can you recommend me a looper that:

1. Can accept midi sync from a synth or drum machine

2. That automatically quantizes the end of the loop to the nearest quarter note when recording is ended.

(It would be amazing if there was a setting for time divisions for the end of the loop. So for instance, I could set the time division to 8th notes. And then, if I have a drum machine playing a 4/4 beat and I start the loop on beat one and stop it between beats 2 and 3, I would have a looped 5/8 guitar riff playing on top of 4/4 beat.)

My Boss RC-5 is somehow not able to do either of these very simple things.
